True or false. If Americans decided to eat more chicken and less beef, the future size of the chicken population would increase

and the cattle population decline. True False True or false. Resources that are commonly owned are likely to be over-utilized and poorly maintained. True False True or false: Ocean fisheries are generally owned in common; as a result, the quantity of various species such as salmon are often overfished.

Answer:

The given first statement is true, that is, with the increase in the demand for chicken, the chicken market will rise, and in the same way with the decline in the demand for beef, the production of cattle will decrease based on the law of demand.  

The given second statement is also true, as the resources mentioned in the given statement is a tragedy of commons as the common access resources are rivalrous and non-excludable.  

The given third statement is also true, as the mentioned ocean fisheries is a tragedy of commons as the common access resources are rivalrous and non-excludable.

Marysya12 [62]

Answer:

Interphase

Explanation:

The phase in which most of the cells appear to be in is interphase.

This is so because cell's life is spent more in interphase and in this phase growth of cells and at the end their replication takes place. So cells get more time in interphase to grow and replicate, which makes more cells to appear to be in.

Hence, the correct answer is "Interphase".

Label each organism in the food web as a producer, consumer, or decomposer. Hope u can help.
ira [324]

Hi, The center image is a decomposer because it decomposes the dead organisms. The grass is a producer since it produces its own energy through photosynthesis. The rest are consumers because they consume other organisms to get energy. Hope that helped!

Two autosomal genes, J and K, are 60 map units apart. You perform the following testcross: J K / j k x j k / j k. At what freque
Dmitry [639]

Answer:

  • J K / j k = 20%
  • j k / j k = 20%
  • J k / j k = 30%
  • j K / j k = 30%                

Explanation:

To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.

The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.

So, en the exposed example:

  • J and K are autosomal genes
  • J and K are separated by 60 M.U.
  • 60 M.U. means that there is 60% of recombination.

Cross)             J K / j k                    x                  j k / j k

Gametes) JK  Parental                                     jk, jk, jk, jk

                jk   Parental                                  

                Jk   Recombinant                          

                 jK   Recombinant

One map unit equals 1% of recombination frequency. This means that every 100 meiotic products, one of them is a recombinant one.

1 M.U. -------------- 1% recombination

60 M.U. ------------ 60% recombination

                              30% Jk  +  30% jK

100 M.U. - 60 M.U. = 40 M.U.

40M.U.--------------40 % Parental (Not recombinant)

                            20% JK   +   20% jk

Punnet Square)           JK       jk      Jk      jK

                          jk     JK/jk   jk/jk   Jk/jk   jK/jk

J K / j k = 20%

j k / j k = 20%

J k / j k = 30%

j K / j k = 30%
